Step 1:
The power is turned off so that it is safe to continue the process.

Step 2:
We block off all supply , and return registers (grilles).

Step 3:
We cut an access into the supply duct where our Negative Air Machine will be attached. This machine is equipped with a high efficiency (HEPA) filter.

Step 4:
Entering into the metal duct at intervals (from furthest to closest towards the negative air machine) we will begin to clean the space.
Using our Cobra III brush which rotates clockwise & counterclockwise, ensures complete cleaning. Connected to the cobra system is an air hose, which is hooked up to a 12.5hp truck mounted compressor. This delivers 175psi which not only allows the brush to agitate any particles, but forces them toward the negative air machine. This continues until all supply ducts are cleaned.

Step 5:
Following the same order as in (4) we will (using our 2600 fogging machine) begin fogging the ducts with "soot-set." This is a non-toxic, nonflammable, air duct adhesive. The dried residual lining in the air ducts (after fogging) resists blow-out of material that may have been impossible to remove during the cleaning process.

Step 6:
Continuing in the same order we will fog the ducts with "sporicidin." This is a sporicide that is anti-bacterial, tuberculocidal, virucidal, and fungicidal. It is also an effective treatment for mold and mildew.

Step 7:
Continuing in the same order we will fog the ducts with a deodorant. This is designed to cause air freshening effects.

Step 8:
After completing step #7, these steps are to be repeated, for the return air ducts. Upon completion of supply and return (cleaning and decontamination) the register (grilles) will be cleaned individually. This is done using a commercial grade de-greaser specifically designed for vents, registers, etc ... In some circumstances this process may be omitted depending on the condition of each grille.
